Dude just stop. Sasuke tried everything he had to kill Naruto, your argument failed the moment sasuke cast amaterasu. Absorbing the bijuu chakra is icing on the cake.umm dude. Sasuke wanted to beat Naruto in a fight with his two hands. Genjutsu are for when you don't feel like fighting or you want to make quick work of somebody. If he didn't wanted that, he would've just become the next Jin right after Kaguya lost control of her form. Sasuke done seen Obito weaved seal signs to become a jin.
Shit the real question is why Madara didn't hit Naruto or Sasuke with genjutsu when he fought them.....
